Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a synthetic corticosteroid with anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory transcription factors (e.g., NF-κB) and increased synthesis of lipocortin-1, which reduces phospholipase A2 activity and subsequent release of arachidonic acid metabolites (prostaglandins, leukotrienes). In the lungs, it decreases airway inflammation by reducing eosinophil infiltration, mast cell degranulation, and cytokine release.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and subsequent anti-inflammatory and immunosuppressive effects. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses cytokine production.
Inhalation aerosol: 88-880 mcg twice daily; typical starting dose: 88 mcg twice daily. Max: 880 mcg twice daily. Oral inhalation powder: 100-1000 mcg twice daily; typical starting: 100 mcg twice daily. Max: 1000 mcg twice daily.
10-60 mg orally once daily or divided twice daily; maximum 60 mg/day.

Approximately 14.4 hours (range 7.8–24.6 hours) for the inhaled route; supports twice-daily dosing; prolonged in hepatic impairment.
Terminal elimination half-life: 2-3 hours (after IV/IM/oral). Clinically, anti-inflammatory effects persist beyond plasma half-life due to glucocorticoid receptor-mediated gene transcription effects.
Primarily hepatic metabolism (CYP3A4) with fecal excretion of metabolites; renal excretion accounts for <5% of the dose as unchanged drug and metabolites combined.
Primarily renal (80-90% as inactive glucuronide and sulfate conjugates; less than 10% as unchanged drug). Biliary/fecal excretion accounts for about 5%.
